Can I compare a field declared as numeric COMP and a normal numeric 9(2) field??
Cheers,
Siva.. |

| No .. Make either of them compatible to other. |

Perhaps something that you might like to try yourself. |

 didn't want to make you people angry ..I have seen instances where Comp fields have been compared to display numeric fields.I ran a small test for this
| Code: |
01 WS-T1 PIC S9(4) COMP VALUE 2.
01 WS-T2 PIC 9(2) VALUE 1.
01 WS-T3 PIC 9(2) VALUE ZEROES.
IF WS-T1 > WS-T2
DISPLAY "NUMERIC VALUE:" WS-T2
END-IF
COMPUTE WS-T3 = WS-T1 + WS-T2
DISPLAY "NUMERIC VALUE2:" WS-T3
NUMERIC VALUE:01
NUMERIC VALUE2:03 |

Oh, really? Here's the code:
| Code: |
05 WS-COMP-1 PIC S9(18) COMP VALUE +12.
05 WS-COMP-2 PIC S9(09) COMP VALUE +12.
05 WS-COMP-3 PIC S9(04) COMP VALUE +12.
05 WS-DISP-1 PIC 9(02) VALUE 12.
/
PROCEDURE DIVISION.
S1000-MAIN SECTION.
IF WS-COMP-1 = WS-DISP-1
DISPLAY 'MATCH 1 EQUAL'
ELSE
DISPLAY 'MATCH 1 UNEQUAL'
END-IF.
IF WS-COMP-2 = WS-DISP-1
DISPLAY 'MATCH 2 EQUAL'
ELSE
DISPLAY 'MATCH 2 UNEQUAL'
END-IF.
IF WS-COMP-3 = WS-DISP-1
DISPLAY 'MATCH 3 EQUAL'
ELSE
DISPLAY 'MATCH 3 UNEQUAL'
END-IF. |
which produces output of
| Code: |
MATCH 1 EQUAL
MATCH 2 EQUAL
MATCH 3 EQUAL |
Siva, Pankaj -- there is a link to the manuals at the top of the page. Click on it, click on the COBOL Language Reference, and find out for sure -- not by guessing -- exactly how the IF statement comparisons are done. Yeah, it'll take some reading and digging on your part but the effort will serve you well in the long run. |
